Letter-s Patent No. 83,455, dated October 27, 1868.

IMPROVEMENT IN HOSE-COUPLINGS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Beit known thatwe, HENRY C. BULL and SAMUEL T. SHELLEY, of Louisville, in the county of J effcrson, and State of Kentueky,have invented a new and useful Improvement in Hose-Couplings fand we do hereby declare that the following is a full and exact description thereof, which will enable any one skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specication, in which-fy Figure 1 is a partial sectional view of the female part of hose-coupling, made according to our invention, extreme end being in full view.

Figure 2 is a partialscctional view of the male part of coupling, showing the mode of making the joint.

Figure 3 is an end view of fig. l of the hose-coupling.

Figures 4 and 5 are side and end news of swivel-band for securing gs. l and 2 together.

Similar letters of reference indicate corresponding.

parts.

This invention relates to an improvement in hosecouplings, and it consists in the meansl employed for forming and tightening the i joints, as will be hereinafter described. Y

A is 'a gum or' other elastic ring, which is placed within the male portion ofthe coupling, and is held in its position by means of a metallic band or ring, as shown at B, fig.` 2. The ring A extends beyond the end of the portion B of the coupling for a distance suflicient to permit it to be pressed firmly against the conical shoulder formed upon the female portion, E,

of the coupling, as shown at f in fig. l.

` B is the band or ring above referred to, which is used to secure the elastic tube a within the male portion, F, of the coupling.

O is the chamber, formed within the female portion,

\ E, of the coupling4 to receive that portion ofthe elastic tube which extends beyond shoulder jl D is a metallicand eccentric-ring, which isfmade to embrace the female portion of the coupling, and it is provided with slots in its interior surface, as shown at` aig.,5, to permit it to pass over the projection e, formed upon the male portion, F, of the coupling, as shown in iig. 2.

E is the female portion of the coupling, the interior diameter of which is of the proper size to receive the i male portion for, say, one-third of its length, at which point its diameter is reduced by having formed within the remaining portion a conical ledge or slmuldenj, against which the elastic ringror tube presses firmly when the two parts are united.

It will be observed that slots, ll, are formed at oppo.

site parts upon this portion of the coupling,vwhich are for the purpose of receiving the priijections upon female portion, and permitting of their longitudinal movement therein as they are pressed upon by the eccentric portions of ring D;

The operation of this device is as follows:

The two parts of the coupling being properly iittcd together, and the ring D placed in its position, the elastic ring or tube is passed into the recess formed in F to receive it, when ring B is pressed within said tube suiiiciently tight to secure it in its vposition when the two parts are put together, which carries the flexible ring within the shoulder j, formed in the female portion, when, if the eccentric-ring Dis turned so as to .bring the eccentric portions thereof in contact with the projections on the male portion, that portion will be pressed toward the shoulder, and thus a tight joint formed.

'lt will be seen that we are enabled to form a perfectly reliable coupling, and one which can be readily connected and disconnected, and which possesses the further advantage of always insuring a tight joint.

Having thus described our invention,

What we claim, and desire to secure by Letters Pat-- ent, isv A hose-coupling, consisting ofthe following elements: 'lhe female portion-E, with its concave shoulder f, the male portion F, having the elastic ring or tube secured therein, and the eccentric-ring l), all constructed and combined substantially as herein described.
